9 Propanal (CH3CH½CHO) is used in the pharmaceutical industry to make essential ingredients,organic chemicals, industrial chemicals, pesticides, and fertilizers. One of the process routes toproduce propanal is via the oxo process by hydroformylation of ethylene using carbon monoxideand hydrogen in the presence of rhodium complex catalyst, according to the following reaction:H,C=CH, + CO + Hz → CH,CH,CH=OIt has been reported that ethylene hydroformylation occurs with a high propanal selectivity, up to99% (Gorbunov et al., 2019). The reversible adsorption of the reactants onto the catalyst surfaceoccurs molecularly, and the reaction kinetics is said to be limited by the irreversible surfacereaction.(a) Determine a rate expression for the overall reaction.

Rate expression is totally dependent upon reactants.
